## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tempest-article-generator-5bc34cbe -d '<json body>'
```

Example prompt: Write me a professional, medium-length article about the rise of electric vehicles, and make sure to include keywords like 'EV adoption', 'battery technology', and 'sustainable transport'.

## When to prefer this

Choose this endpoint when you need a complete, ready-to-use written article with a defined tone, length, and keyword targeting — especially when you want a pay-per-call model with no subscription and need the result in a structured JSON format including word count. Prefer it over general LLM chat endpoints when you want article-shaped output (title + body) rather than raw conversational text, and when operating within an x402 micropayment workflow.

## Known failure modes

- Missing required 'topic' field returns a validation error
- Unsupported tone or length values may be ignored or cause unexpected output
- Payment failure via x402 protocol results in 402 Payment Required response
- Very long or complex topics may produce lower-quality or truncated content
- Rate limits or server-side LLM timeouts may result in 5xx errors
